Animacy perception arises in human adults from motion cues implying an internal energy source to the moving object. The internal energy of the object is often represented by a change in speed. The same features cause preferential attention in infants. We investigated whether speed changes affecting adults’ animacy ratings elicit spontaneous social preferences in visually-naïve chicks. Human observers...
This paper presents a multi-sensor system for the detection of people falls in the home environment. Two kinds of devices are used: a MEMS wearable wireless accelerometer with onboard fall detection algorithms and a 3D Time-of-Flight camera. An embedded computing system receives the possible fall alarm data from the two sub-sensory systems and their associated level of confidence. The computing module...
In this paper we present a wearable wireless accelerometer device for people fall detection in ambient assisted living (AAL) applications, communicating with care holders and relatives of the assisted person through an ADSL based gateway. The wearable system is a PCB with a commercial three-axes, digital-output MEMS accelerometer chip, a ZigBee transceiver and a programmable logic (FPGA). The raw...
The paper proposes new technologies to support independence and engagement in elderly people living alone at home in the framework of a new UE Integrated Project. Aim of the study is the development of a light technological infrastructure to be integrated in the homes of old people at reduced costs, allowing the detection of critical health situations. In particular a reliable fall detector is presented,...
